TeSys LX0FJ010 Contactor Coil, 380-400 V AC, Active

The LX0FJ010: The control circuit voltage is 380-400 V AC 50/60 Hz. That means the coil is designed for a line-to-line or line-to-neutral supply at those levels — common in European 400 V three-phase panels. The voltage limits are 0.85 to 1.1 times Uc for both latching and unlatching, so the coil holds in reliably down to about 323 V and up to 440 V. If your control voltage is 24 V DC or 230 V, this is not the coil you need. Operating time is 50-100 ms unlatching and 40-75 ms latching. That is typical for a contactor coil of this size — fast enough for motor starting and general switching, but not for high-speed applications like inverter bypass contactors that need sub-20 ms response. That rate is fine for most pump, fan, and conveyor duty; if you are cycling a load every 30 seconds continuously, you will exceed the rating. The coil resistance is 94.8 ohms for the latching winding and 9380 ohms for the unlatching winding at 20 °C. The high unlatching resistance means the holding current is low once the contactor is sealed — the coil driver only needs to supply a brief inrush for latching, then a much lower current to keep it closed. That is standard for AC-operated contactor coils with a separate unlatching (holding) circuit.
